GMC Sierra 1500 Speakers Upgrade
We installed new speakers into this massive GMC Sierra 1500. This was a huge upgrade to his old speakers. The customer came to us looking for a little more boom to his truck and we gave it to him by putting in a JL Audio JX500/1D 500RMS JX series mono amplifier and a JL Audio CP108LG-W3V3 loaded sub enclosure and a JL Audio microsub single 8 inch W3 ported. The upgrade was a terrific addition to his truck.
